Astaxanthin reduces eye fatigue

Vision of computer users improves – it becomes sharper, tension in the eyes and stiffness in the neck and back are reduced, eyes are better able to refocus on various distances!
Today people spend about 45 hours per week looking at a screen – be it a computer, television or smartphone. This has given rise to a new diagnosis – Computer Vision Syndrome. The most widespread symptoms are dry, tired, irritated and painful eyes, blurred vision and neck and shoulder pain. Eyes get tired because continuous concentration on the screen disrupts circulation and creates a landslide of free radicals. In order to offset the disrupted circulation and lack of oxygen, capillaries expand – this results in redness of the eyes. Some capillaries cannot take the pressure and burst causing discomfort and pain in the eyes. If nothing is done about it, tissue and muscle in the eyes continues to break down.

Several randomized double blind placebo controlled studies conducted in Japan have shown promising results. These unpleasant symptoms are reduced after 4 weeks of supplementing astaxanthin

For example, a study by Nagaki et al (2002) demonstrated that after 5 months of supplementing astaxanthin 54% of subjects reported reduced subjective symptoms of eye strain:  fatigue, dryness, blurred vision (n=26). The placebo group did not display any change (n=13)1. The reduction of eye strain after supplementing astaxanthin has been attested not only by personal observations of the subjects, but also through objective measurements. For example, in a study by Nitta et al (n=30) after 4 weeks of supplementing astaxanthin (6mg and 12mg per day) accommodation amplitude improved.1 2 3 4 6 7. Other studies have obtained similar result3 4 5 6 7.

Astaxanthin improves capillary circulation in the eyes

We have all heard about bilberries, which contain lutein that improves eye health. The antioxidant astaxanthin, which is obtained from microalgae, is much more active.
It is 28 times more powerful in terms of improving vision than the traditional bilberry supplements. The antioxidant astaxanthin has been recognised as an innovation in vision enhancing supplements. Due to its fine molecule it can easily penetrate the retina, where it absorbs the harmful rays of blue light and neutralises free radicals.

Low antioxidant levels and reduced blood flow are the main reasons that can cause disruption of capillary circulation. Circulation in the retina is the very foundation of the internal balance in the eye. Good circulation ensures that the eye is properly supplied with oxygen, waste products are removed and the eye receives nutrients.

After 4 weeks of supplementing astaxanthin (6mg per day) the blood antioxidant level increased significantly and capillary circulation improved in both eyes (n=18). The placebo group showed no change (n=18)8.

Astaxanthin reduces inflammation in the eyes in vitro and in vivo.

The positive effects of astaxanthin are based in its antioxidative properties. The main cause of oxidative stress is sunlight, which contains UV rays, which in turn create free radicals. All tissue exposed to light is subjected to such photooxidative damage.
The eyes and the skin are the most vulnerable tissue. Furthermore, the retina contains a lot of polyunsaturated fatty acids and therefore it is very quickly damaged by UV rays. UV damage is the main cause of two of the most common diseases leading to impaired vision and blindness – age-related macular degeneration and age-related nuclear cataract. Antioxidants fight these adverse processes. The eye contains only a couple of antioxidants – those that can penetrate the fine blood-retinal barrier, and astaxanthin, due to its fine molecule can easily access the retina. As a result less free radicals are created due to UV glare, and the less free radicals there are, the less inflammation inducers are activated.

Two studies came to the same conclusion – astaxanthin displays anti-inflammatory effects in the iris of the eye – the ciliary muscle. Astaxanthin suppressed free radical induced activation of NF-kB, which causes and amplifies inflammation. The result was a lower pro-inflammatory response9. Another study demonstrated the anti-inflammatory properties of astaxanthin in endotoxin-induced uveitis10. The researchers explained that astaxanthin’s ability to reduce the number of inflamed cells in the iris is one of the reasons why it alleviates symptoms of eye fatigue.

Astaxanthin delays onset of presbyopia

Presbyopia (age-related farsightedness) is caused by the reduced ability to focus on near objects due to loss of elasticity of the crystalline lens after age 45. A study showed that after supplementing 6 mg of astaxanthin 77% of subjects felt an improvement in seeing nearby objects and a decrease in blurred vision.
This was followed by alleviation of eye strain and shoulder stiffness. Improvements were also documented by objective measurements. The pupillary constriction ratio, used to assess the accommodative function of the eye, showed an overall improvement of 19% after supplementation of astaxanthin. Indicators improved just two weeks in to the study.

Therefore, the researchers concluded that astaxanthin may slow down the progression of presbyopia in middle-aged and elderly people11.

In another study volunteers were given different doses of astaxanthin (0 mg, 2 mg, 4 mg and 12 mg per day). After ingestion of astaxanthin for 28 consecutive days, the uncorrected far visual acuity significantly improved in groups receiving 4 mg and 12 mg doses. Statistically viable improvement was also documented for accommodation amplitude/speed (refocusing from near to far objects and vice versa)12.

For healthy, beautiful, age defying skin

Skin is the largest organ of the body and it is extremely complex. It consists of multiple layers with each layer having unique functions. Products that are applied to the surface of the skin predominantly affect the epidermis, the outermost layer of the skin, and are limited in their ability to penetrate into deeper layers of the skin.

Natural astaxanthin, which is obtained from freshwater microalgae, is the most powerful antioxidant known to science. It is deemed to be the most powerful agent in the anti-aging industry, which is worth billions, it is incorporated into many prestigious anti-aging products and recommended by leading skincare specialists. 

Clinical research shows that natural astaxanthin significantly improves all layers of skin by protecting them against their main enemy – free radicals. The result is improved health of the skin; its natural beauty and radiance is revealed. Scientific evidence has been found explaining why astaxanthin significantly reduces wrinkles. The secret is astaxanthin’s ability to stimulate regeneration of collagen fibres. Collagen tissue ensures skin strength and elasticity, gives it a youthful and smooth appearance. The fine weave of collagen fibres is damaged by UV radiation and the massive production of free radicals that it induces. Astaxanthin reduces the effects of reactive oxygen molecules, thus allowing collagen to maintain its ability to regenerate.

Clinical benefits of natural astaxanthin:    

  • Revitalises photoaged skin by quenching oxidative stress and inflammation in all skin layers 

  • Reduces age spots by quenching overproduction and oxidation of melanin

  • Reduces the size of wrinkles and improves skin microtexture

  • Improves elasticity in the skin by strengthening the collagen layer


Vision and eye health

Astaxanthin is the newest dietary supplement for improved eye health. Various clinical studies have shown that astaxanthin supplementation together with other health improving measures can improve the symptoms linked to Computer Vision Syndrome (also known as the silent pandemic) – dry, tired or watery and aching eyes, blurred vision and neck and shoulder pain.

Any tissue that is subjected to light is affected by UV radiation and the photooxidative damage it causes; the retina is especially vulnerable as it contains many polyunsaturated fatty acids. UV damage is the main cause of two of the most common diseases leading to impaired vision and blindness – age-related macular degeneration and age-related nuclear cataract.

Antioxidants fight adverse processes, however, the eye contains only a couple of antioxidants – those that can penetrate the fine blood-retinal barrier, and astaxanthin is one of them. The result – less free radicals are formed due to UV glare and eye inflammation inducers are activated less. This is beneficial not only for the elderly, whose eyes have already seen so much in this life, but also for all the computer users out there.

Clinical studies have found natural astaxanthin to improve eye health and vision by: 

  • improving blood circulation in the fine blood vessels in the eye (capillary circulation);
  • relieving symptoms of Computer Vision Syndrome and eye fatigue;
  • improving the eye’s ability and speed to focus on objects at various distances;
  • reducing inflammation of the eye’s internal or ciliary muscle.


Physical endurance and fat metabolism

Intense physical activity and training lead to increased oxidative stress in the body. This can result in increased damage to red blood cells and the activation of inflammatory pathways, negatively impacting the recovery time and performance of muscles.

Natural astaxanthin improves endurance during physical activity by improving aerobic power. It is a powerful antioxidant and also has anti-inflammatory effects. Studies have found that supplementing astaxanthin can reduce lactic acid build-up, delay fatigue and reduce muscle atrophy in seniors.

Benefits of astaxanthin for muscle performance:

  • Boosts muscle endurance and recovery
  • Lowers lactic acid and fatigue
  • Reduces muscle damage and inflammation
  • Improves blood flow and the quality of red blood cells
  • Enhances fat metabolism by improving mitochondria function


Cardiovascular health

Clinical and experimental research has concluded that natural astaxanthin can contribute to improved cardiovascular health. It reduces oxidative stress and inflammation, improves lipid profiles and capillary circulation.

Benefits of astaxanthin for cardiovascular health:

  • Improves blood lipid profiles
  • Reduces oxidative stress
  • Enhances capillary circulation



The immune system functions better when it is protected. Immune cells are particularly sensitive to misbalance of antioxidants in the body as they contain many polyunsaturated fatty acids which are fragile and easily damaged by oxidative stress.

Natural astaxanthin protects the immune system against free radicals, thus maintaining its ability to function properly. It balances and strengthens the immune system at the same time. It enhances the body’s defences, whilst also helping to supress the overactive immune responses that create unwanted inflammation.

Benefits of natural astaxanthin for the immune system:

  • Faster immune response
  • Strengthens and balances the immune system
  • Enhances production of antibodies
  • Protects immune cells against oxidative stress


Brain health

A number of studies have concluded that astaxanthin induces several biological processes in the brain. A randomised double-blind, placebo-controlled study showed that 3-month supplementation of astaxanthin (12 mg) improved mental quickness, multitasking, memory and faster learning in senior subjects complaining of age-related forgetfulness.

Benefits of natural astaxanthin for brain health:

  • Reduces age-related forgetfulness, improves alertness and multitasking
  • Decreases oxidation of red blood cells, which is linked to prevention of dementia
  • Enhances capillary circulation and blood antioxidant quality
  • Modulates blood pressure lowering the risk of stroke and improves vascular endothelial health


Gastric health

The digestive system is one of the most sensitive components of the human body. Clinical studies have shown that astaxanthin supplementation can support gastric health due to its ability to inhibit gastric inflammation, provide protection against stomach ulcers and reduce Helicobacter pylori infection.

Benefits of natural astaxanthin for stomach health:

  • Lowers gastric inflammation
  • Decreases infection of H.pylori
  • Reduces clinical symptoms in dyspepsia patients
